Description

U+28D8, also known as Braille Pattern Dots-4578, is a critical character within the Unicode standard that plays a pivotal role in digital text for the visually impaired. This character represents one of the possible configurations of six dots arranged in a 3x2 matrix that forms the basis of the Braille writing system. Invented by Louis Braille in the early 19th century, this tactile writing system allows individuals with visual impairments to read and write using their sense of touch. The Braille Pattern Dots-4578 is utilized to represent specific characters or words in various languages that have been adapted for Braille, including English, French, and many others. By encoding text into these patterns of dots, individuals with visual impairments can access information independently and efficiently. As an essential part of digital text for the visually impaired, U+28D8 and other Braille characters significantly contribute to inclusivity in digital communication and education.

How to type the symbol on Windows

Hold Alt and type 10456 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character has the Unicode code point U+28D8. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of 0x0800 to 0xffff.

    Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format: 1110xxxx 10xxxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+28D8 to binary: 00101000 11011000. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
